RE: 99 Suburban Tire Size?
No matter how loaded it has been, or what I have been towing with it, I have never experienced any tire rub on my vehicle. The only drawback that I have encountered with this upgrade is trying to explain to my wife that the vehicle is actually travelling almost 10% faster than indicated by the speedometer. She is a full throttle and full brake kind of driver.
Hope that helps,
